ADB-FUBIATA (AD-18, FUB-ACADB, ADB-FUBIACA) is a synthetic cannabinoid compound first identified in 2021. It is closely related in structure to the older compound ADB-FUBICA but with the amide linker group extended by the addition of a methylene bridge. It started to be sold as an ingedient in grey-market synthetic cannabis blends following the introduction of legislation in China which for the first time introduced general controls on various classes of synthetic cannabinoids,[1] but did not encompass compounds where the linker group had been extended in this fashion. ADB-FUBIATA has many times lower affinity for cannabinoid receptors than ADB-FUBICA with an EC50 of only 635 nM at CB1, but retains full agonist activity at this target, while being practically inactive at CB2.[2][3]
